Lock.

To all whom it may concern Be it known that I, GEORGE A. VVEHNER, a citizen of the United States, and a resident of Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention is an improvement in looks, and has for its object to provide a lockof the permutation type, wherein a bolt is provided, and a casing upon which the bolt is mounted to move diametrically thereof, the casing having a rotatable member provided with means for locking the bolt in looking position, the bolt being normally spring released and the lock member being also normally spring released, and wherein a series of push buttons is provided in connection with the casing, normally spring held in outward position and capable of being depressed, sundry of the buttons being positive and others negative in their action, and the arrangement being such that when the positive buttons are simultaneously depressed the locking mechanism for the bolt will be released, while when any negative'button is depressed it will impede and prevent any rellease of the locking mechanism for the be t.

In the drawings, Figure l is a front view of the improved lock with the bolt in look ing position; Fig. 2 is a'similar view with the bolt in a position of release; Figs. 3, 4-,

tudinally movable sectional bolt 11 which is adapted to cooperate with a catch 2, in the form of a reinforced recess into which one end of the bolt is adapted to extend to lock the parts which it is desired to lock together.

Q The cylindrical casing comprises a 'cup shaped body comprising a disk 3 and a lateral marginal flange 4, and a cover plate 5,

which is secured to the cup-shaped body by means of a central or axial screw 6. This screw is passed through the center of the disk 3 into engagement with a threaded opening in the cover 5, and the bolt 11'" moves diametrically of the cover. The said bolt has its side edges undercut, as. shown at 7, in Fig. 10, and the bolt moves between segmental guide plates 8 secured to the rear face of the cover plate 5, and having their inner straight edges undercut. The plates are held to the cover plate by screws 9.

The spring 10, which moves the bolt into release position, and which normally holds the bolt in such position, is connectedwith the section 1 of the bolt, the said section having a laterally extending pin 11.to which one end of the spring 10 is connected, and the other end of the spring is connected to a pin 12extending rearwardly from the flange 4 of the cup-shaped body of the casing.

A species of wheelis mounted to rotate bolt, while a coiledspring 18 is connected with the latter pin, the said spring acting normally to hold the wheel in aposition of release. p

The spring 18 is connected at its outer end to a pin 19 connected with the flange 4 of the casing, adjacent to the pin 12, before mentioned. The disk 15 is'provided with a series of radial arms 20, and each arm has at its outerend an angular lock 21, the said lock extendingtoward the body 3 of the casing.

A disk 22 is journaled on the screw 6 in front of the disk 13 of the wheel, and the said disk 22 is provided with a series of radial openings or recesses 23 in its periphery. The push buttons 25 and 25 are movable in these openings. Each of these buttons, to b later described, has its inner end'rounded as shown at 24, to engage the adjacent recess, and the disk 22 supports and guides the buttons in their movement. The bodies of the buttons 25 and 25 extend through slots 26 in the flange 4 of thecover, and each button has a head 27 at its outer end for engagement by the finger of the operator when it is desired to depress the button. The buttons are normally held in outward position by spring arms 28 on a disk 29 held on the screw 6 in front .of the disk 22. These arms 28 are resilient, and the said arms extend radially from the disk.

Each arm engages at its outer end an inclined or cam surface 30 on the front edge of the adjacent button, between the rounded portion 21 of the button and the body thereof. hen the buttons are depressed, as shown in Fig. 9, the resilient arms 28 are pressed forwardly or outwardly toward the body 3 of the cover of the casing, and it will be evident that as .soon as the buttons are released the resilience of the .arms will force them again outward.

The angular portions 21 of the arms 20 are looking members for engaging the push buttons, and the said buttons are adapted to engage the wheel 1314l-15 to permit release of the bolt. Each of the positive push buttons 25 is provided in its rear edge with a notch or recess 31, which, when the button is depressed, will register with the locks 21 of the disk 15. hen the buttons 25 are in outward position, however, these locks 21 will engage just within the notches 31, thus preventing the angular movement of the said disk with respect to the buttons and their supports. The negative buttons 25 when in outward position do not engage the locks 21, each button being cut away, as indicated at 31, to pass the locks. hen the buttons are depressed, however, they will block the movement of the disk 15.

All of the buttons are held in place in the casing, and are limited as to their outward movement, by means of a retaining ring 32, which is slipped onto the flange 1 in rear of the buttons, as shown more particularly in Figs. 8, 9 and 11 Each of the buttons has a shoulder 33 on the rear edge and just outside the cam surface 30, the said shoulder being formed by reducing the body from the shoulder outward, and these shoulders 33 engage the retaining ring, as shown in Fig. 11, to limit the outward movement of the buttons.

A washer 34. is arranged between the disk 29 and the cup-shaped body of the casing, to properly space the disks 13, 141, 15, 22 and 29, the said washer encircling the screw 6. The spring 18 normally holds the locking wheel constituted by the disks 131 115 in a position of release as regards the bolt 1-1 and the said wheel is moved into engaging position, by an angular lug 35 on the inner end of the section 1 of the bolt.

This lug 35 when the bolt 11 is moved into locking position, engages the pin 17 before mentioned, of the disk 14: and swings or oscillates the disk in a direction to cause the pin 16 to engage a recess or rabbet 36 at the inner end of the bolt section 1. j

The spring 10, which tends to draw the bolt 1-1 into a position of release, holds the rabbet or recess in contact with the pin 16, thus preventing release of the said pin until the wheel is released by the movement of the push buttons. 7

Referring to Figs. 8 and 9, it will be seen that the locks of the disk 15 when the buttons 25 and 25 are in normal position,'cannot move angularly because the said locks will engage the positive buttons 25. The buttons 25, however, do not interfere with the locks 21 when the said buttons 25 are in normal position, and it is only when the said buttons 25 are moved inwardly that they come into position to interfere with the locks.

Certain predetermined buttons are positive buttons, being similar to the buttons 25, and normally standing in position to block the angular movement of the disk 15, and these positive buttons must be pressed inward to release the disk 15. If any other button than the positive buttons is pressed inward, the release of the disk 15 will be again blocked by the movement of the negative buttons. Hence, the positive buttons and the positive buttons only must be depressed to release the lock. 4

A stop 37 is provided for limiting the movement of the disk 14- in one direction, that is, toward a position of release, and the engagement of the pin 16 with the inner surface of the rabbet or notch 36 would limit the movement of the disk in the opposite direction. A filling washer 38 is arranged between the disk 15 and the cover plate 5, the washer encircling the screw 6, and being cut away at the side adjacent to the springs 10 and 18 to prevent interference therewith. This washer has an eccentric opening 39 which is engaged by a pin 40 on the cover plate'5 to prevent angular movement of the washer.

In operation, when it is desired to lock the receptacle, or whatever is to be locked, the bolt 11 will move against the resistance of the spring 10 in a direction to cause one end thereof to engage the recess. As the bolt moves, the lug 35 on the section 1 of V the bolt engages the pin 17 of the disk 14,

and swings or oscillates the wheel 13 1 1 15 in a direction to cause the pin 16 to engage the shoulder or rabbet 36 of the section 1 of the bolt, thus locking the bolt in locked position, as shown in Figs. 1 and 8.

lVhenever it is desired to release the bolt, the positive or predetermined series of push buttons is depressed. These positive buttons normally standas shown at the top of Fig. 8, and it will be evident that as long as they do stand in this position, the disk 15 cannot be rotated, that is, the locking wheel will stand in the position of Fig. 7, holding the bolt in locked position. Whenever these buttons are depressed, however, as indicated in Fig. 9, they offer no impediment to the angular movement of the wheel 13--1l15, and as soon as the wheel is released, the spring 18 will return the wheel to normal position, that is, with the pin 17 in engagement with the stop 37, and with the pin 16 out of position to interfere with the movement of the bolt. The belt is immediately moved into open position by the spring '10. Should oneof the negative but tons be depressed, the said buttons will interfere with the moven'ient of the locking wheel, and it cannot return to normal position under the influence of the spring.

It will be evident from the description that to release the bolt the combination must be known, and only the positive buttons must be depressed. The depression of a single negative button will prevent the release of the bolt.

The improved lock is designed for use with any character of receptacle or door, wherein a straight moving bolt is required.

It is obvious that by slight changes in the form of the bolt, evidentto any one skilled in the art, the bolt might be monifiedto provide chest lock or the like.

The section 1 of the bolt is entirely detached and independent of the section 1?. This section is in fact a push button or slide for operating the bolt proper. It is obvious that this section might be made detachable if desired, since it has no function in the combination other than as an actuating member during the locking of the bolt, and

as an actuating member for the locking.

mechanism for the bolt.

The section i of the bolt is provided with two shoulders, one the shoulder 36 before mentioned and the other a shoulder 36 at the outer side of the shoulder 36. In a position of release, the pin 16 engages the shoulder 36, while in locking position the pin engages the shoulder 36. These shoulders are so arranged as to not interfere with the movement of the locking wheel. It Will be noted that the pin 16 extends between two arms 20 of the disk 15, thus constraining the disks la: and 15 to move together. The disks 14 and 15 are the only portions of the lock that are necessarily rotatable, and the disk 13 is a filling or spacing disk, as are also the washers 34c and 38.

In the embodiment of the invention shown in Figs. 12 to 14:, the lock comprises a bolt $1 in the form of a plate, one end of the bolt being adapted to engage a reinforced recess like that shown in Figs. 8

and 9, to lock the parts which are to be locked. The bolt is slidably mounted on the body portion of a plate having an angular portion H at the outer end of the bolt, and the bolt is guided on the plate by means of headed pins or screws and 45, on the plate 43, and engaging longitudinally extending slots 46 and 4-7 in the bolt. The bolt is normally moved into release position by means of'a coiled spring 48, Which engages at one end a headed pin or screw 49 on the plate -l3 and extending through the slot l7, and at the other end the spring en-' gages a laterally and upwardly extending ing 51 on a latch plate 52 at the front end of the bolt. This latch plate has an angular lug 53 at its forward end, extending inwardly and transversely of the front end of the slot 4-7, and the said lug is pivoted to the bolt by-a screw The rear end of the latch is free to swing laterally, into and out of position to engage a pin 55 on a locking disk 56 which is mounted to rotate onthe plate -13, on the opposite side from the bolt. This pin extends through an arc-shaped slot 57 in the plate i3 andthrough an opening 58 in the bolt, andthe spring 48 normally acts to move the latch plate into engagement with. the'pin. This spring, ho\vever, normally holds the bolt'in a position of release, and the boltmust be moved into locking position before the latch plate can engage with the pin 55; As soon as the rear end of the latch plate moves past the pin 55, the spring 48 swings the latch plate to cause the rear end to move infront of the pin, thus preventing release movement'of the bolt.

The latch plate is limited in its swinging movement by means of-a pin 59 connected with the bolt and extending upwardly through a longitudinal recess or notch 60 in the rearend of the plate. It will be noticed that this recess or notch has an. extension 60 at its inner end and extending toward the pin 55, the arrangementbeing such that the latch plate may swing out.

ward far enough to release the pin 55. Tie locking disk 56 is normally moved into a position of release by a coiled spring 61 arranged on the opposite side of the disk from the plate 43, between a pin 52011 the disk and a pin on the support 64- for the look. This pin 62 extends outwardly through registering notches 65 in the plate 43 and the bolt. and it will be evident that the engagement of the pin with the ends of the notches would limit the movement of the disk with respect to the bolt, as shown in Fig. 13.

The latch plate 52 has its inner side clined or cam shaped-to cause. the latch plate to be moved outwardly when it engages the pin 55, in order that the pin may pass be yond. the outer end of. the latch plate to engage the same. The locking disk 56 is provided with an angular lug 66 at its periphery, the lug extending in the opposite direction to the bolt, and this lug is adapted to engage push buttons, to prevent the release of the locking mechanism. These buttons 67, but one of which is shown, are arranged in positive and negative series. Each button moves through a slot 68 in the angular portion a of the plate, and through a guide 69 on the support 6%, the buttons being guided by the guide and the angular portion 14 of the plate, 43. Each button has a head 70 at its outer end, and a plate spring 71 is provided for each button to normally hold the button in outward position.

As shown, the springs 71 are secured t the support 64: at their inner ends and at its outer end each has a return bend portion 72 which engages a cam surface 73 on the push button. At the outer end of each cam surface a shoulder 74 is provided for engaging the angular portion 1 1 of the plate to limit the outward movement of the button. A retaining plate or ring 75 is arranged outside of the angular portion at of the plate 48, to hold the buttons in place. and each button has a notch or recess 7 6 at the edge adjacent to the locking disk 56 for engagement by the lug (S5 of the disk to prevent angular movement of the disk in a direction to release the bolt.

The buttons are arranged in the same manner as those shown in Figs. 1 to 11, that is, in such manner that when a positive button is pressed inward the notch 76 will register with the lug 65, while when a negative button is pressed inward the notch 7 6 will be out of register with the lug 65. The negative buttons normally stand with their notches 76 in register with the lug 65.

It will be obvious that as many buttons may be pro-vided as may be necessary or thought advisable, the buttons being arranged as shown for a single button.

In each construction the lock comprises in its simplest form a bolt spring pressed normally into a position of release, a lock for the bolt normally spring pressed into a position of release, together with positive buttons arranged to hold the locking mechanism in looking position and release the same when depressed, and with negative buttons normally in position of release, but

arranged to block the movement of the locking mechanism when the said buttons are depressed.

It will be noted from an inspection of Figs. 1 and 2, that the front of the casing, that is, the outer face of the lock casing is provided with an annular series of numerals consecutively arranged, and running in the present instance, from 1 to 12. The numerals are arranged in an annular series,

at the periphery of the casing, and at the respective push buttons. The lock shown is arranged to be operated by the buttons adjacent to the numerals 1, 3, 5 and 9, and these positive buttons are shown depressed in Figs. 2, 4. and 9, and in position to release the locking wheel.

It is obvious that the buttons might be designated in any other desired manner, or they mav be without designations if desired. The combination may be easily changed by changing the buttons.

Since all of the positive buttons are alike, and the negative buttons are alike, and since any button may be arranged in any one of the radial slots of the casing, the buttons may be arranged precisely as desired. The buttons are similar in all respects with the single exception of the notch 31 and cut away portion 31, and any button of either series will fit in the place of any other button of the same series or of the other series.

In order to change the combination, the sections are released by removing the cover plate hen now, the retaining ring is slipped 0d the flange f of the casing, any one or all of the buttons may be detached. They are held in place solely by the retaining ring and if this ring is removed, any or all of the buttons may be taken out and they may 7 be replaced in any desired order.

It will be evident from the above that the combination is easily and quickly changed, and it may be changed as often as desired.

In the construction of Figs. 12 to 14, in practice the buttons will be held in precisely the same manner and may be varied as to arrangement whenever desired.

In Fig. 15 mechanism is shown for permitting the bolt to be moved into locking position from the front of the casing of the lock. This mechanism is desirable when for any reason the section 1 of the bolt is not accessible to close the bolt. The said mechanism comprises an eccentric pin 81 on one face of a disk 80 and secured to a shaft '82, the shaft being axial to the disk. lVith this arrangement the screw (3 will be tubular. and the shaft 82 will be iournaled in the screw, with the disk 80 between the disk 38 and the bolt, and with the pin 81 extending between the sections of the bolt, in a recess provided for this purpose in the inner end of the section 1. The pin engages the inner end of the section 1, and it will be evident that when the disk is oscillated by means of the shaft in the direction of the arrow shown in Fig. 15, the section 1* will be moved into locking position by the pin 81. The outer end of the shaft 82 will be provided with a knob or head to facilitate the rotation of the shaft.
